SpringCloud微服务实战——搭建企业级开发框架（二十三）：Gateway+OAuth2+JWT实现微服务统一认证授权

OAuth2是一个关于授权的开放标准，核心思路是通过各类认证手段（具体什么手段OAuth2不关心）认证用户身份，并颁发token（令牌），使得第三方应用可以使用该token（令牌）在限定时间、限定范围访问指定资源。

OAuth2中使用token验证用户登录合法性，但token最大的问题是不携带用户信息，资源服务器无法在本地进行验证，每次对于资源的访问，资源服务器都需要向认证服务器发起请求，一是验证token的有效性，二是获取token对应的用户信息。如果有大量的此类请求，无疑处理效率是很低，且认证服务器会变成一个中心节点，这在分布式架构下很影响性能。如果认证服务器颁发的是jwt格式的token，那么资源服务器就可以直接自己验证token的有效性并绑定用户，这无疑大大提升了处理效率且减少了单点隐患。

SpringCloud认证授权解决思路：认证服务负责认证，网关负责校验认证和鉴权，其他API服务负责处理自己的业务逻辑。安全相关的逻辑只存在于认证服务和网关服务中，其他服务只是单纯地提供服务而没有任何安全相关逻辑。

微服务鉴权功能划分：

gitegg-oauth：Oauth2用户认证和单点登录
gitegg-gateway：请求转发和统一鉴权
gitegg-system: 读取系统配置的RBAC权限配置并存放到缓存

一、鉴权配置

1、GitEgg-Platform工程下新建gitegg-platform-oauth2工程，用于统一管理OAuth2版本，及统一配置

2、在gitegg-oauth工程中引入需要的库

<!--?xml version="1.0" encoding="UTF-8"?-->

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemalocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

    </dependencies>

</project>

3、JWT可以使用HMAC算法或使用RSA的公钥/私钥对来签名，防止被篡改。首先我们使用keytool生成RSA证书gitegg.jks，复制到gitegg-oauth工程的resource目录下，CMD命令行进入到JDK安装目录的bin目录下, 使用keytool命令生成gitegg.jks证书

keytool -genkey -alias gitegg -keyalg RSA -keystore gitegg.jks

4、新建GitEggUserDetailsServiceImpl.java实现SpringSecurity获取用户信息接口,用于SpringSecurity鉴权时获取用户信息

package com.gitegg.oauth.service;

import javax.servlet.http.HttpServletRequest;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.security.core.authority.AuthorityUtils;

import org.springframework.security.core.userdetails.UserDetailsService;

import org.springframework.security.core.userdetails.UsernameNotFoundException;

import org.springframework.security.oauth2.common.exceptions.UserDeniedAuthorizationException;

import org.springframework.stereotype.Service;

import org.springframework.util.CollectionUtils;

import org.springframework.util.StringUtils;

import com.gitegg.oauth.enums.AuthEnum;

import com.gitegg.platform.base.constant.AuthConstant;

import com.gitegg.platform.base.domain.GitEggUser;

import com.gitegg.platform.base.enums.ResultCodeEnum;

import com.gitegg.platform.base.result.Result;

import com.gitegg.service.system.api.feign.IUserFeign;

import cn.hutool.core.bean.BeanUtil;

import lombok.RequiredArgsConstructor;

/**

 *  实现SpringSecurity获取用户信息接口

 *

 * @author gitegg

 */

@Service

@RequiredArgsConstructor(onConstructor = @__(@Autowired))

public class GitEggUserDetailsServiceImpl implements UserDetailsService {

    private final IUserFeign userFeign;

    private final HttpServletRequest request;

    @Override

    public GitEggUserDetails loadUserByUsername(String username) {

        // 获取登录类型，密码，二维码，验证码

        String authLoginType = request.getParameter(AuthConstant.AUTH_TYPE);

        // 获取客户端id

        String clientId = request.getParameter(AuthConstant.AUTH_CLIENT_ID);

        // 远程调用返回数据

        Result<object> result;

        // 通过手机号码登录

        if (!StringUtils.isEmpty(authLoginType) && AuthEnum.PHONE.code.equals(authLoginType))

        {

            String phone = request.getParameter(AuthConstant.PHONE_NUMBER);

            result = userFeign.queryUserByPhone(phone);

        }

        // 通过账号密码登录

        else if(!StringUtils.isEmpty(authLoginType) && AuthEnum.QR.code.equals(authLoginType))

        {

            result = userFeign.queryUserByAccount(username);

        }

        else

        {

            result = userFeign.queryUserByAccount(username);

        }

        // 判断返回信息

        if (null != result && result.isSuccess()) {

            GitEggUser gitEggUser = new GitEggUser();

            BeanUtil.copyProperties(result.getData(), gitEggUser, false);

            if (gitEggUser == null || gitEggUser.getId() == null) {

                throw new UsernameNotFoundException(ResultCodeEnum.INVALID_USERNAME.msg);

            }

            if (CollectionUtils.isEmpty(gitEggUser.getRoleIdList())) {

                throw new UserDeniedAuthorizationException(ResultCodeEnum.INVALID_ROLE.msg);

            }

            return new GitEggUserDetails(gitEggUser.getId(), gitEggUser.getTenantId(), gitEggUser.getOauthId(),

                gitEggUser.getNickname(), gitEggUser.getRealName(), gitEggUser.getOrganizationId(),

                gitEggUser.getOrganizationName(),

                    gitEggUser.getOrganizationIds(), gitEggUser.getOrganizationNames(), gitEggUser.getRoleId(), gitEggUser.getRoleIds(), gitEggUser.getRoleName(), gitEggUser.getRoleNames(),

                gitEggUser.getRoleIdList(), gitEggUser.getRoleKeyList(), gitEggUser.getResourceKeyList(),

                gitEggUser.getDataPermission(),

                gitEggUser.getAvatar(), gitEggUser.getAccount(), gitEggUser.getPassword(), true, true, true, true,

                AuthorityUtils.createAuthorityList(gitEggUser.getRoleIdList().toArray(new String[gitEggUser.getRoleIdList().size()])));

        } else {

            throw new UsernameNotFoundException(result.getMsg());

        }

    }

}

5、新建AuthorizationServerConfig.java用于认证服务相关配置，正式环境请一定记得修改gitegg.jks配置的密码，这里默认为123456。TokenEnhancer 为登录用户的扩展信息，可以自己定义。

package com.gitegg.oauth.config;

import java.security.KeyPair;

import java.util.ArrayList;

import java.util.HashMap;

import java.util.List;

import java.util.Map;

import javax.sql.DataSource;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.beans.factory.annotation.Value;

import org.springframework.context.annotation.Bean;

import org.springframework.context.annotation.Configuration;

import org.springframework.core.io.ClassPathResource;

import org.springframework.data.redis.core.RedisTemplate;

import org.springframework.security.authentication.AuthenticationManager;

import org.springframework.security.core.userdetails.UserDetailsService;

import org.springframework.security.oauth2.common.DefaultOAuth2AccessToken;

import org.springframework.security.oauth2.config.annotation.configurers.ClientDetailsServiceConfigurer;

import org.springframework.security.oauth2.config.annotation.web.configuration.AuthorizationServerConfigurerAdapter;

import org.springframework.security.oauth2.config.annotation.web.configuration.EnableAuthorizationServer;

import org.springframework.security.oauth2.config.annotation.web.configurers.AuthorizationServerEndpointsConfigurer;

import org.springframework.security.oauth2.config.annotation.web.configurers.AuthorizationServerSecurityConfigurer;

import org.springframework.security.oauth2.provider.TokenGranter;

import org.springframework.security.oauth2.provider.token.TokenEnhancer;

import org.springframework.security.oauth2.provider.token.TokenEnhancerChain;

import org.springframework.security.oauth2.provider.token.store.JwtAccessTokenConverter;

import org.springframework.security.oauth2.provider.token.store.KeyStoreKeyFactory;

import com.anji.captcha.service.CaptchaService;

import com.gitegg.oauth.granter.GitEggTokenGranter;

import com.gitegg.oauth.service.GitEggClientDetailsServiceImpl;

import com.gitegg.oauth.service.GitEggUserDetails;

import com.gitegg.platform.base.constant.AuthConstant;

import com.gitegg.platform.base.constant.TokenConstant;

import com.gitegg.service.system.api.feign.IUserFeign;

import lombok.RequiredArgsConstructor;

import lombok.SneakyThrows;

/**

 * 认证服务配置

 */

@Configuration

@EnableAuthorizationServer

@RequiredArgsConstructor(onConstructor_ = @Autowired)

public class AuthorizationServerConfig extends AuthorizationServerConfigurerAdapter {

    private final DataSource dataSource;

    private final AuthenticationManager authenticationManager;

    private final UserDetailsService userDetailsService;

    private final IUserFeign userFeign;

    private final RedisTemplate redisTemplate;

    private final CaptchaService captchaService;

    @Value("${captcha.type}")

    private String captchaType;

    /**

     * 客户端信息配置

     */

    @Override

    @SneakyThrows

    public void configure(ClientDetailsServiceConfigurer clients) {

        GitEggClientDetailsServiceImpl jdbcClientDetailsService = new GitEggClientDetailsServiceImpl(dataSource);

        jdbcClientDetailsService.setFindClientDetailsSql(AuthConstant.FIND_CLIENT_DETAILS_SQL);

        jdbcClientDetailsService.setSelectClientDetailsSql(AuthConstant.SELECT_CLIENT_DETAILS_SQL);

        clients.withClientDetails(jdbcClientDetailsService);

    }

    /**

     * 配置授权（authorization）以及令牌（token）的访问端点和令牌服务(token services)

     */

    @Override

    public void configure(AuthorizationServerEndpointsConfigurer endpoints) {

        TokenEnhancerChain tokenEnhancerChain = new TokenEnhancerChain();

        List<tokenenhancer> tokenEnhancers = new ArrayList<>();

        tokenEnhancers.add(tokenEnhancer());

        tokenEnhancers.add(jwtAccessTokenConverter());

        tokenEnhancerChain.setTokenEnhancers(tokenEnhancers);

        // 获取自定义tokenGranter

        TokenGranter tokenGranter = GitEggTokenGranter.getTokenGranter(authenticationManager, endpoints, redisTemplate,

            userFeign, captchaService, captchaType);

        endpoints.authenticationManager(authenticationManager)

                .accessTokenConverter(jwtAccessTokenConverter())

                .tokenEnhancer(tokenEnhancerChain)

                .userDetailsService(userDetailsService)

            .tokenGranter(tokenGranter)

                /**

                 *

                 * refresh_token有两种使用方式：重复使用(true)、非重复使用(false)，默认为true

                 * 1.重复使用：access_token过期刷新时， refresh token过期时间未改变，仍以初次生成的时间为准

                 * 2.非重复使用：access_token过期刷新时， refresh_token过期时间延续，在refresh_token有效期内刷新而无需失效再次登录

                 */

                .reuseRefreshTokens(false);

    }

    /**

     * 允许表单认证

     */

    @Override

    public void configure(AuthorizationServerSecurityConfigurer security) {

        security.allowFormAuthenticationForClients()

                .tokenKeyAccess("permitAll()")

                .checkTokenAccess("isAuthenticated()");

    }

    /**

     * 使用非对称加密算法对token签名

     */

    @Bean

    public JwtAccessTokenConverter jwtAccessTokenConverter() {

        JwtAccessTokenConverter converter = new JwtAccessTokenConverter();

        converter.setKeyPair(keyPair());

        return converter;

    }

    /**

     * 从classpath下的密钥库中获取密钥对(公钥+私钥)

     */

    @Bean

    public KeyPair keyPair() {

        KeyStoreKeyFactory factory = new KeyStoreKeyFactory(

                new ClassPathResource("gitegg.jks"), "123456".toCharArray());

        KeyPair keyPair = factory.getKeyPair(

                "gitegg", "123456".toCharArray());

        return keyPair;

    }

    /**

     * JWT内容增强

     */

    @Bean

    public TokenEnhancer tokenEnhancer() {

        return (accessToken, authentication) -> {

            Map<string, object=""> map = new HashMap<>(2);

            GitEggUserDetails user = (GitEggUserDetails) authentication.getUserAuthentication().getPrincipal();

            map.put(TokenConstant.TENANT_ID, user.getTenantId());

            map.put(TokenConstant.OAUTH_ID, user.getOauthId());

            map.put(TokenConstant.USER_ID, user.getId());

            map.put(TokenConstant.ORGANIZATION_ID, user.getOrganizationId());

            map.put(TokenConstant.ORGANIZATION_NAME, user.getOrganizationName());

            map.put(TokenConstant.ORGANIZATION_IDS, user.getOrganizationIds());

            map.put(TokenConstant.ORGANIZATION_NAMES, user.getOrganizationNames());

            map.put(TokenConstant.ROLE_ID, user.getRoleId());

            map.put(TokenConstant.ROLE_NAME, user.getRoleName());

            map.put(TokenConstant.ROLE_IDS, user.getRoleIds());

            map.put(TokenConstant.ROLE_NAMES, user.getRoleNames());

            map.put(TokenConstant.ACCOUNT, user.getAccount());

            map.put(TokenConstant.REAL_NAME, user.getRealName());

            map.put(TokenConstant.NICK_NAME, user.getNickname());

            map.put(TokenConstant.ROLE_ID_LIST, user.getRoleIdList());

            map.put(TokenConstant.ROLE_KEY_LIST, user.getRoleKeyList());

            //不把权限菜单放到jwt里面,当菜单太多时，会导致jwt长度不可控

//            map.put(TokenConstant.RESOURCE_KEY_LIST, user.getResourceKeyList());

            map.put(TokenConstant.DATA_PERMISSION, user.getDataPermission());

            map.put(TokenConstant.AVATAR, user.getAvatar());

            ((DefaultOAuth2AccessToken) accessToken).setAdditionalInformation(map);

            return accessToken;

        };

    }

}

6、Gateway在认证授权时需要RSA的公钥来验证签名是否合法，所以这里新建GitEggOAuthController的getKey接口用于Gateway获取RSA公钥

    @GetMapping("/public_key")

    public Map<string, object=""> getKey() {

        RSAPublicKey publicKey = (RSAPublicKey) keyPair.getPublic();

        RSAKey key = new RSAKey.Builder(publicKey).build();

        return new JWKSet(key).toJSONObject();

    }

7、新建ResourceServerConfig.java资源服务器配置，放开public_key的读取权限

	@Override

	@SneakyThrows

	public void configure(HttpSecurity http) {

		http.headers().frameOptions().disable();

		http.formLogin()

			.and()

			.authorizeRequests().requestMatchers(EndpointRequest.toAnyEndpoint()).permitAll()

			.and()

			.authorizeRequests()

			.antMatchers(

				"/oauth/public_key").permitAll()

			.anyRequest().authenticated()

			.and()

			.csrf().disable();

	}

8、在gitegg-service-system新建InitResourceRolesCacheRunner.java实现CommandLineRunner接口，用于系统启动时加载RBAC权限配置信息到缓存

package com.gitegg.service.system.component;

import java.util.*;

import java.util.stream.Collectors;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.beans.factory.annotation.Value;

import org.springframework.boot.CommandLineRunner;

import org.springframework.data.redis.core.RedisTemplate;

import org.springframework.stereotype.Component;

import com.gitegg.platform.base.constant.AuthConstant;

import com.gitegg.service.system.entity.Resource;

import com.gitegg.service.system.service.IResourceService;

import cn.hutool.core.collection.CollectionUtil;

import lombok.RequiredArgsConstructor;

import lombok.extern.slf4j.Slf4j;

/**

 * 容器启动完成加载资源权限数据到缓存

 */

@Slf4j

@RequiredArgsConstructor(onConstructor_ = @Autowired)

@Component

public class InitResourceRolesCacheRunner implements CommandLineRunner {

    private final RedisTemplate redisTemplate;

    private final IResourceService resourceService;

    /**

     * 是否开启租户模式

     */

    @Value(("${tenant.enable}"))

    private Boolean enable;

    @Override

    public void run(String... args) {

        log.info("InitResourceRolesCacheRunner running");

        // 查询系统角色和权限的关系

        List<resource> resourceList = resourceService.queryResourceRoleIds();

        // 判断是否开启了租户模式，如果开启了，那么角色权限需要按租户进行分类存储

        if (enable) {

            Map<long, list<resource="">> resourceListMap =

                resourceList.stream().collect(Collectors.groupingBy(Resource::getTenantId));

            resourceListMap.forEach((key, value) -> {

                String redisKey = AuthConstant.TENANT_RESOURCE_ROLES_KEY + key;

                redisTemplate.delete(redisKey);

                addRoleResource(redisKey, value);

                System.out.println(redisTemplate.opsForHash().entries(redisKey).size());

            });

        } else {

            redisTemplate.delete(AuthConstant.RESOURCE_ROLES_KEY);

            addRoleResource(AuthConstant.RESOURCE_ROLES_KEY, resourceList);

        }

    }

    private void addRoleResource(String key, List<resource> resourceList) {

        Map<string, list<string="">> resourceRolesMap = new TreeMap<>();

        Optional.ofNullable(resourceList).orElse(new ArrayList<>()).forEach(resource -> {

            // roleId -> ROLE_{roleId}

            List<string> roles = Optional.ofNullable(resource.getRoleIds()).orElse(new ArrayList<>()).stream()

                .map(roleId -> AuthConstant.AUTHORITY_PREFIX + roleId).collect(Collectors.toList());

            if (CollectionUtil.isNotEmpty(roles)) {

                resourceRolesMap.put(resource.getResourceUrl(), roles);

            }

        });

        redisTemplate.opsForHash().putAll(key, resourceRolesMap);

    }

}

9、新建网关服务gitegg-gateway，作为Oauth2的资源服务、客户端服务使用，对访问微服务的请求进行转发、统一校验认证和鉴权操作，引入相关依赖

<!--?xml version="1.0" encoding="UTF-8"?-->

10、新建AuthResourceServerConfig.java对gateway网关服务进行配置安全配置，需要使用@EnableWebFluxSecurity而非@EnableWebSecurity,因为SpringCloud Gateway基于WebFlux

package com.gitegg.gateway.config;

import org.springframework.context.annotation.Bean;

import org.springframework.context.annotation.Configuration;

import cn.hutool.core.util.ArrayUtil;

import lombok.AllArgsConstructor;

import reactor.core.publisher.Mono;

/**

@AllArgsConstructor

@Configuration

public class AuthResourceServerConfig {

    private final AuthorizationManager authorizationManager;

    private final WhiteListRemoveJwtFilter whiteListRemoveJwtFilter;

    @Bean

    public SecurityWebFilterChain securityWebFilterChain(ServerHttpSecurity http) {

        http.oauth2ResourceServer().jwt()

                .jwtAuthenticationConverter(jwtAuthenticationConverter());

        // 自定义处理JWT请求头过期或签名错误的结果

        http.oauth2ResourceServer().authenticationEntryPoint(authServerAuthenticationEntryPoint);

        // 对白名单路径，直接移除JWT请求头，不移除的话，后台会校验jwt

        http.addFilterBefore(whiteListRemoveJwtFilter, SecurityWebFiltersOrder.AUTHENTICATION);

        http.authorizeExchange()

            .pathMatchers(ArrayUtil.toArray(authUrlWhiteListProperties.getUrls(), String.class)).permitAll()

                .anyExchange().access(authorizationManager)

                .and()

                .exceptionHandling()

                .accessDeniedHandler(authServerAccessDeniedHandler) // 处理未授权

                .authenticationEntryPoint(authServerAuthenticationEntryPoint) //处理未认证

                .and()

                .cors()

                .and().csrf().disable();

        return http.build();

    }

    /**

     * ServerHttpSecurity没有将jwt中authorities的负载部分当做Authentication，需要把jwt的Claim中的authorities加入

     * 解决方案：重新定义ReactiveAuthenticationManager权限管理器，默认转换器JwtGrantedAuthoritiesConverter

     */

    @Bean

    public Converter<jwt, ?="" extends="" mono<?="" abstractauthenticationtoken="">> jwtAuthenticationConverter() {

        JwtGrantedAuthoritiesConverter jwtGrantedAuthoritiesConverter = new JwtGrantedAuthoritiesConverter();

        jwtGrantedAuthoritiesConverter.setAuthorityPrefix(AuthConstant.AUTHORITY_PREFIX);

        jwtGrantedAuthoritiesConverter.setAuthoritiesClaimName(AuthConstant.AUTHORITY_CLAIM_NAME);

        JwtAuthenticationConverter jwtAuthenticationConverter = new JwtAuthenticationConverter();

        jwtAuthenticationConverter.setJwtGrantedAuthoritiesConverter(jwtGrantedAuthoritiesConverter);

        return new ReactiveJwtAuthenticationConverterAdapter(jwtAuthenticationConverter);

    }

}

11、新建AuthorizationManager.java实现ReactiveAuthorizationManager接口，用于自定义权限校验

package com.gitegg.gateway.auth;

import java.util.ArrayList;

import java.util.Iterator;

import java.util.List;

import java.util.Map;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.beans.factory.annotation.Value;

import org.springframework.data.redis.core.RedisTemplate;

import org.springframework.http.HttpMethod;

import org.springframework.http.server.reactive.ServerHttpRequest;

import org.springframework.security.authorization.AuthorizationDecision;

import org.springframework.security.authorization.ReactiveAuthorizationManager;

import org.springframework.security.core.Authentication;

import org.springframework.security.core.GrantedAuthority;

import org.springframework.security.web.server.authorization.AuthorizationContext;

import org.springframework.stereotype.Component;

import org.springframework.util.AntPathMatcher;

import org.springframework.util.PathMatcher;

import org.springframework.util.StringUtils;

import com.gitegg.platform.base.constant.AuthConstant;

import cn.hutool.core.convert.Convert;

import lombok.RequiredArgsConstructor;

import lombok.extern.slf4j.Slf4j;

import reactor.core.publisher.Mono;

/**

 * 网关鉴权管理器

 */

@Slf4j

@Component

@RequiredArgsConstructor(onConstructor_ = @Autowired)

public class AuthorizationManager implements ReactiveAuthorizationManager<authorizationcontext> {

    private final RedisTemplate redisTemplate;

    /**

     * 是否开启租户模式

     */

    @Value(("${tenant.enable}"))

    private Boolean enable;

    @Override

    public Mono<authorizationdecision> check(Mono<authentication> mono, AuthorizationContext authorizationContext) {

        ServerHttpRequest request = authorizationContext.getExchange().getRequest();

        String path = request.getURI().getPath();

        PathMatcher pathMatcher = new AntPathMatcher();

        // 对应跨域的预检请求直接放行

        if (request.getMethod() == HttpMethod.OPTIONS) {

            return Mono.just(new AuthorizationDecision(true));

        }

        // token为空拒绝访问

        String token = request.getHeaders().getFirst(AuthConstant.JWT_TOKEN_HEADER);

        if (StringUtils.isEmpty(token)) {

            return Mono.just(new AuthorizationDecision(false));

        }

        //  如果开启了租户模式，但是请求头里没有租户信息，那么拒绝访问

        String tenantId = request.getHeaders().getFirst(AuthConstant.TENANT_ID);

        if (enable && StringUtils.isEmpty(tenantId)) {

            return Mono.just(new AuthorizationDecision(false));

        }

        String redisRoleKey = AuthConstant.TENANT_RESOURCE_ROLES_KEY;

        // 判断是否开启了租户模式，如果开启了，那么按租户分类的方式获取角色权限

        if (enable) {

            redisRoleKey += tenantId;

        } else {

            redisRoleKey = AuthConstant.RESOURCE_ROLES_KEY;

        }

        //  缓存取资源权限角色关系列表

        Map<object, object=""> resourceRolesMap = redisTemplate.opsForHash().entries(redisRoleKey);

        Iterator<object> iterator = resourceRolesMap.keySet().iterator();

        //请求路径匹配到的资源需要的角色权限集合authorities统计

        List<string> authorities = new ArrayList<>();

        while (iterator.hasNext()) {

            String pattern = (String) iterator.next();

            if (pathMatcher.match(pattern, path)) {

                authorities.addAll(Convert.toList(String.class, resourceRolesMap.get(pattern)));

            }

        }

        Mono<authorizationdecision> authorizationDecisionMono = mono

                .filter(Authentication::isAuthenticated)

                .flatMapIterable(Authentication::getAuthorities)

                .map(GrantedAuthority::getAuthority)

                .any(roleId -> {

                    // roleId是请求用户的角色(格式:ROLE_{roleId})，authorities是请求资源所需要角色的集合

                    log.info("访问路径：{}", path);

                    log.info("用户角色roleId：{}", roleId);

                    log.info("资源需要权限authorities：{}", authorities);

                    return authorities.contains(roleId);

                })

                .map(AuthorizationDecision::new)

                .defaultIfEmpty(new AuthorizationDecision(false));

        return authorizationDecisionMono;

    }

}

12、新建AuthGlobalFilter.java全局过滤器，解析用户请求信息，将用户信息及租户信息放在请求的Header中，这样后续服务就不需要解析JWT令牌了，可以直接从请求的Header中获取到用户和租户信息。

package com.gitegg.gateway.filter;

import java.io.UnsupportedEncodingException;

import java.net.URLEncoder;

import java.text.ParseException;

import java.util.HashMap;

import java.util.Map;

import java.util.function.Consumer;

import org.springframework.beans.factory.annotation.Value;

import org.springframework.cloud.gateway.filter.GatewayFilterChain;

import org.springframework.cloud.gateway.filter.GlobalFilter;

import org.springframework.core.Ordered;

import org.springframework.http.HttpHeaders;

import org.springframework.http.server.reactive.ServerHttpRequest;

import org.springframework.stereotype.Component;

import org.springframework.web.server.ServerWebExchange;

import com.gitegg.platform.base.constant.AuthConstant;

import com.nimbusds.jose.JWSObject;

import cn.hutool.core.util.StrUtil;

import lombok.extern.slf4j.Slf4j;

import reactor.core.publisher.Mono;

/**

 * 将登录用户的JWT转化成用户信息的全局过滤器

 */

@Slf4j

@Component

public class AuthGlobalFilter implements GlobalFilter, Ordered {

    /**

     * 是否开启租户模式

     */

    @Value(("${tenant.enable}"))

    private Boolean enable;

    @Override

    public Mono<void> filter(ServerWebExchange exchange, GatewayFilterChain chain) {

        String tenantId = exchange.getRequest().getHeaders().getFirst(AuthConstant.TENANT_ID);

        String token = exchange.getRequest().getHeaders().getFirst(AuthConstant.JWT_TOKEN_HEADER);

        if (StrUtil.isEmpty(tenantId) && StrUtil.isEmpty(token)) {

            return chain.filter(exchange);

        }

        Map<string, string=""> addHeaders = new HashMap<>();

        // 如果系统配置已开启租户模式，设置tenantId

        if (enable && StrUtil.isEmpty(tenantId)) {

            addHeaders.put(AuthConstant.TENANT_ID, tenantId);

        }

        if (!StrUtil.isEmpty(token)) {

        try {

            //从token中解析用户信息并设置到Header中去

            String realToken = token.replace("Bearer ", "");

            JWSObject jwsObject = JWSObject.parse(realToken);

            String userStr = jwsObject.getPayload().toString();

            log.info("AuthGlobalFilter.filter() User:{}", userStr);

            addHeaders.put(AuthConstant.HEADER_USER, URLEncoder.encode(userStr, "UTF-8"));

        } catch (ParseException | UnsupportedEncodingException e) {

            e.printStackTrace();

        }

    }

    Consumer<httpheaders> httpHeaders = httpHeader -> {

        addHeaders.forEach((k, v) -> {

            httpHeader.set(k, v);

        });

    };

    ServerHttpRequest request = exchange.getRequest().mutate().headers(httpHeaders).build();

    exchange = exchange.mutate().request(request).build();

        return chain.filter(exchange);

    }

    @Override

    public int getOrder() {

        return 0;

    }

}

13、在Nacos中添加权限相关配置信息：

spring:

  jackson:

    time-zone: Asia/Shanghai

    date-format: yyyy-MM-dd HH:mm:ss

  security:

    oauth2:

      resourceserver:

        jwt:

          jwk-set-uri: 'http://127.0.0.1/gitegg-oauth/oauth/public_key'

# 多租户配置

tenant:

  # 是否开启租户模式

  enable: true

  # 需要排除的多租户的表

  exclusionTable:

    - "t_sys_district"

    - "t_sys_tenant"

    - "t_sys_role"

    - "t_sys_resource"

    - "t_sys_role_resource"

  # 租户字段名称

  column: tenant_id

# 网关放行白名单，配置白名单路径

white-list:

  urls:

    - "/gitegg-oauth/oauth/public_key"

二、注销登录使JWT失效

因为JWT是无状态的且不在服务端储存，所以，当系统在执行退出登录时就无法使JWT失效，我们有两种方式拒绝注销登录后的JWT：

JWT白名单：每次登录成功就将JWT存到缓存中，缓存有效期和JWT有效期保持一致，注销登录就将JWT从缓存中移出。Gateway每次认证授权先从缓存JWT白名单中获取是否存在该JWT，存在则继续校验，不存在则拒绝访问。
JWT黑名单：每当注销登录时，将JWT存到缓存中，解析JWT的到期时间，将缓存过期时间设置为和JWT一致。Gateway每次认证授权先从缓存中获取JWT是否存在于黑名单中，存在则拒绝访问，不存在则继续校验。

不管是白名单还是黑名单，实现方式的原理都基本一致，就是将JWT先存放到缓存，再根据不同的状态进行判断JWT是否有效，下面是两种方式的优缺点分析：

黑名单功能分析：优点是存放到缓存的数据量将小于白名单方式存放的数据量，缺点是无法获知当前签发了多少JWT，当前在线多少登录用户。
白名单功能分析：优点是当我们需要统计在线用户的时候，白名单方式可以近似的获取到当前系统登录用户，可以扩展踢出登录用户的功能。缺点是数据存储量大，且大量token存在缓存中需要进行校验，万一被攻击会导致大量信息泄露。

综上考虑，还是采用黑名单的方式来实现注销登录功能，实时统计在线人数和踢出用户等功能作为扩展功能来开发，不在登录注销逻辑中掺杂太多的业务处理逻辑，使系统保持低耦合。

为了使JWT有效信息最大程度保证准确性，注销登录除了在系统点击退出登录按钮，还需要监测是否直接关闭页面，关闭浏览器事件，来执行调用系统注销接口。

token和refresh_token的过期时间不一致，都在其解析之后的exp字段。因为我们定制了黑名单模式，当用户点击退出登录之后，我们会把refresh_token也加入黑名单，在refresh_token获取刷新token的时候，需要定制校验refresh_token是否被加入到黑名单。

1、退出登录接口将token和refresh_token加入黑名单

        /**

     * 退出登录需要需要登录的一点思考：

     * 1、如果不需要登录，那么在调用接口的时候就需要把token传过来，且系统不校验token有效性，此时如果系统被攻击，不停的大量发送token，最后会把redis充爆

     * 2、如果调用退出接口必须登录，那么系统会调用token校验有效性，refresh_token通过参数传过来加入黑名单

     * 综上：选择调用退出接口需要登录的方式

     * @param request

     * @return

     */

    @PostMapping("/logout")

    public Result logout(HttpServletRequest request) {

        String token = request.getHeader(AuthConstant.JWT_TOKEN_HEADER);

        String refreshToken = request.getParameter(AuthConstant.REFRESH_TOKEN);

        long currentTimeSeconds = System.currentTimeMillis() / GitEggConstant.Number.THOUSAND;

        // 将token和refresh_token同时加入黑名单

        String[] tokenArray = new String[GitEggConstant.Number.TWO];

        tokenArray[GitEggConstant.Number.ZERO] = token.replace("Bearer ", "");

        tokenArray[GitEggConstant.Number.ONE] = refreshToken;

        for (int i = GitEggConstant.Number.ZERO; i < tokenArray.length; i++) {

            String realToken = tokenArray[i];

            JSONObject jsonObject = JwtUtils.decodeJwt(realToken);

            String jti = jsonObject.getAsString("jti");

            Long exp = Long.parseLong(jsonObject.getAsString("exp"));

            if (exp - currentTimeSeconds > GitEggConstant.Number.ZERO) {

                redisTemplate.opsForValue().set(AuthConstant.TOKEN_BLACKLIST + jti, jti, (exp - currentTimeSeconds), TimeUnit.SECONDS);

            }

        }

        return Result.success();

    }

2、Gateway在AuthorizationManager中添加token是否加入黑名单的判断

        //如果token被加入到黑名单，就是执行了退出登录操作，那么拒绝访问

        String realToken = token.replace("Bearer ", "");

        try {

            JWSObject jwsObject = JWSObject.parse(realToken);

            Payload payload = jwsObject.getPayload();

            JSONObject jsonObject = payload.toJSONObject();

            String jti = jsonObject.getAsString("jti");

            String blackListToken = (String)redisTemplate.opsForValue().get(AuthConstant.TOKEN_BLACKLIST + jti);

            if (!StringUtils.isEmpty(blackListToken)) {

                return Mono.just(new AuthorizationDecision(false));

            }

        } catch (ParseException e) {

            e.printStackTrace();

        }

3、自定义DefaultTokenService，校验refresh_token是否被加入黑名单

@Slf4j

public class GitEggTokenServices extends DefaultTokenServices {

    private final RedisTemplate redisTemplate;

    public GitEggTokenServices(RedisTemplate redisTemplate)

    {

        this.redisTemplate = redisTemplate;

    }

    @Transactional(

            noRollbackFor = {InvalidTokenException.class, InvalidGrantException.class}

    )

    @Override

    public OAuth2AccessToken refreshAccessToken(String refreshTokenValue, TokenRequest tokenRequest) throws AuthenticationException {

        JSONObject jsonObject = null;

        String jti = null;

        //如果refreshToken被加入到黑名单，就是执行了退出登录操作，那么拒绝访问

        try {

            JWSObject jwsObject = JWSObject.parse(refreshTokenValue);

            Payload payload = jwsObject.getPayload();

            jsonObject = payload.toJSONObject();

            jti = jsonObject.getAsString(TokenConstant.JTI);

            String blackListToken = (String)redisTemplate.opsForValue().get(AuthConstant.TOKEN_BLACKLIST + jti);

            if (!StringUtils.isEmpty(blackListToken)) {

                throw new InvalidTokenException("Invalid refresh token (blackList): " + refreshTokenValue);

            }

        } catch (ParseException e) {

            log.error("获取refreshToken黑名单时发生错误：{}", e);

        }

       OAuth2AccessToken oAuth2AccessToken = super.refreshAccessToken(refreshTokenValue, tokenRequest);

        // RefreshToken不支持重复使用，如果使用一次，则加入黑名单不再允许使用，当刷新token执行完之后，即校验过RefreshToken之后，才执行存redis操作

        if (null != jsonObject && !StringUtils.isEmpty(jti)) {

            long currentTimeSeconds = System.currentTimeMillis() / GitEggConstant.Number.THOUSAND;

            Long exp = Long.parseLong(jsonObject.getAsString(TokenConstant.EXP));

            if (exp - currentTimeSeconds > GitEggConstant.Number.ZERO) {

                redisTemplate.opsForValue().set(AuthConstant.TOKEN_BLACKLIST + jti, jti, (exp - currentTimeSeconds), TimeUnit.SECONDS);

            }

        }

        return oAuth2AccessToken;

    }

}

测试：

1、使用密码模式获取token

Headers里面加TenantId:0参数

2、通过refresh_token刷新token

3、再次执行refresh_token刷新token，此时因为refresh_token已经调用过一次，所以这里不能再次使用

三、前端自动使用refresh_token刷新token

1、使用axios-auth-refresh公共组件，当后台状态返回401时，进行token刷新操作

import axios from 'axios'

import createAuthRefreshInterceptor from 'axios-auth-refresh'

import store from '@/store'

import storage from 'store'

import { serialize } from '@/utils/util'

import notification from 'ant-design-vue/es/notification'

import modal from 'ant-design-vue/es/modal'

import { VueAxios } from './axios'

import { ACCESS_TOKEN, REFRESH_ACCESS_TOKEN } from '@/store/mutation-types'

// 创建 axios 实例

const request = axios.create({

  // API 请求的默认前缀

  baseURL: process.env.VUE_APP_API_BASE_URL,

  timeout: 30000 // 请求超时时间

})

// 当token失效时，需要调用的刷新token的方法

const refreshAuthLogic = failedRequest =>

  axios.post(process.env.VUE_APP_API_BASE_URL + '/gitegg-oauth/oauth/token',

  serialize({ client_id: process.env.VUE_APP_CLIENT_ID,

      client_secret: process.env.VUE_APP_CLIENT_SECRET,

      grant_type: 'refresh_token',

      refresh_token: storage.get(REFRESH_ACCESS_TOKEN)

    }),

    {

      headers: { 'TenantId': process.env.VUE_APP_TENANT_ID, 'Content-Type': 'application/x-www-form-urlencoded' }

    }

    ).then(tokenRefreshResponse => {

      if (tokenRefreshResponse.status === 200 && tokenRefreshResponse.data && tokenRefreshResponse.data.success) {

        const result = tokenRefreshResponse.data.data

        storage.set(ACCESS_TOKEN, result.tokenHead + result.token, result.expiresIn * 1000)

        storage.set(REFRESH_ACCESS_TOKEN, result.refreshToken, result.refreshExpiresIn * 1000)

        failedRequest.response.config.headers['Authorization'] = result.tokenHead + result.token

      }

      return Promise.resolve()

})

// 初始化刷新token拦截器

createAuthRefreshInterceptor(request, refreshAuthLogic, {

  pauseInstanceWhileRefreshing: true // 当刷新token执行时，暂停其他请求

})

// 异常拦截处理器

const errorHandler = (error) => {

  if (error.response) {

    const data = error.response.data

    if (error.response.status === 403) {

      notification.error({

        message: '禁止访问',

        description: data.message

      })

    } else if (error.response.status === 401 && !(data.result && data.result.isLogin)) {

      // 当刷新token超时，则调到登录页面

      modal.warn({

        title: '登录超时',

        content: '由于您长时间未操作， 为确保安全， 请重新登录系统进行后续操作 ！',

        okText: '重新登录',

        onOk () {

            store.dispatch('Timeout').then(() => {

                window.location.reload()

            })

         }

      })

    }

  }

  return Promise.reject(error)

}

// request interceptor

request.interceptors.request.use(config => {

  const token = storage.get(ACCESS_TOKEN)

  // 如果 token 存在

  // 让每个请求携带自定义 token 请根据实际情况自行修改

  if (token) {

    config.headers['Authorization'] = token

  }

  config.headers['TenantId'] = process.env.VUE_APP_TENANT_ID

  return config

}, errorHandler)

// response interceptor

request.interceptors.response.use((response) => {

  const res = response.data

  if (res.code) {

    if (res.code !== 200) {

      notification.error({

        message: '操作失败',

        description: res.msg

      })

      return Promise.reject(new Error(res.msg || 'Error'))

    } else {

      return response.data

    }

  } else {

    return response

  }

}, errorHandler)

const installer = {

  vm: {},

  install (Vue) {

    Vue.use(VueAxios, request)

  }

}

export default request

export {

  installer as VueAxios,

  request as axios

}

四、记住密码功能实现

有时候，在我们在可信任的电脑上可以实现记住密码功能，前后端分离项目的实现只需要把密码记录到localstorage中，然后每次访问登录界面时，自动填入即可。这里先使用明文进行存储，为了系统安全，在实际应用过程需要将密码加密存储，后台校验加密后的密码

1、在created中读取是否记住密码

created () {

    this.queryCaptchaType()

      this.$nextTick(() => {

        const rememberMe = storage.get(process.env.VUE_APP_TENANT_ID + '-' + process.env.VUE_APP_CLIENT_ID + '-rememberMe')

          if (rememberMe) {

            const username = storage.get(process.env.VUE_APP_TENANT_ID + '-' + process.env.VUE_APP_CLIENT_ID + '-username')

            const password = storage.get(process.env.VUE_APP_TENANT_ID + '-' + process.env.VUE_APP_CLIENT_ID + '-password')

            if (username !== '' && password !== '') {

            this.form.setFieldsValue({ 'username': username })

            this.form.setFieldsValue({ 'password': password })

            this.form.setFieldsValue({ 'rememberMe': true })

          }

        }

      })

  },

2、每次登录成功之后，根据是否勾选记住密码来确定是否填入用户名密码

     // 判断是否记住密码

      const rememberMe = this.form.getFieldValue('rememberMe')

      const username = this.form.getFieldValue('username')

      const password = this.form.getFieldValue('password')

      if (rememberMe && username !== '' && password !== '') {

          storage.set(process.env.VUE_APP_TENANT_ID + '-' + process.env.VUE_APP_CLIENT_ID + '-username', username, 60 * 60 * 24 * 7 * 1000)

          storage.set(process.env.VUE_APP_TENANT_ID + '-' + process.env.VUE_APP_CLIENT_ID + '-password', password, 60 * 60 * 24 * 7 * 1000)

          storage.set(process.env.VUE_APP_TENANT_ID + '-' + process.env.VUE_APP_CLIENT_ID + '-rememberMe', true, 60 * 60 * 24 * 7 * 1000)

      } else {

         storage.remove(process.env.VUE_APP_TENANT_ID + '-' + process.env.VUE_APP_CLIENT_ID + '-username')

         storage.remove(process.env.VUE_APP_TENANT_ID + '-' + process.env.VUE_APP_CLIENT_ID + '-password')

         storage.remove(process.env.VUE_APP_TENANT_ID + '-' + process.env.VUE_APP_CLIENT_ID + '-rememberMe')

      }

五、密码尝试次数过多则锁定账户

从系统安全方面来讲，我们需要支持防止用户账户被暴力破解的措施，目前技术已经能够轻松破解大多数的验证码，这为暴力破解用户账户提供了方便，那么这里我们的系统需要密码尝试次数过多锁定账户的功能。SpringSecurity的UserDetails接口定义了isAccountNonLocked方法来判断账户是否被锁定

public interface UserDetails extends Serializable {

    Collection<!--? extends GrantedAuthority--> getAuthorities();

    String getPassword();

    String getUsername();

    boolean isAccountNonExpired();

    boolean isAccountNonLocked();

    boolean isCredentialsNonExpired();

    boolean isEnabled();

}

1、自定义LoginFailureListener事件监听器，监听SpringSecurity抛出AuthenticationFailureBadCredentialsEvent异常事件，使用Redis计数器，记录账号错误密码次数

/**

 * 当登录失败时的调用，当密码错误过多时，则锁定账户

 * @author GitEgg

 * @date 2021-03-12 17:57:05

 **/

@Slf4j

@Component

@RequiredArgsConstructor(onConstructor_ = @Autowired)

public class LoginFailureListener implements ApplicationListener<authenticationfailurebadcredentialsevent> {

    private final UserDetailsService userDetailsService;

    private final RedisTemplate redisTemplate;

    @Value("${system.maxTryTimes}")

    private int maxTryTimes;

    @Override

    public void onApplicationEvent(AuthenticationFailureBadCredentialsEvent event) {

        if (event.getException().getClass().equals(UsernameNotFoundException.class)) {

            return;

        }

        String userName = event.getAuthentication().getName();

        GitEggUserDetails user = (GitEggUserDetails) userDetailsService.loadUserByUsername(userName);

        if (null != user) {

            Object lockTimes = redisTemplate.boundValueOps(AuthConstant.LOCK_ACCOUNT_PREFIX + user.getId()).get();

            if(null == lockTimes || (int)lockTimes <= maxTryTimes){

                redisTemplate.boundValueOps(AuthConstant.LOCK_ACCOUNT_PREFIX + user.getId()).increment(GitEggConstant.Number.ONE);

            }

        }

    }

}

2、GitEggUserDetailsServiceImpl方法查询Redis记录的账号锁定次数

            // 判断账号是否被锁定（账户过期，凭证过期等可在此处扩展）

            Object lockTimes = redisTemplate.boundValueOps(AuthConstant.LOCK_ACCOUNT_PREFIX + gitEggUser.getId()).get();

            boolean accountNotLocked = true;

            if(null != lockTimes && (int)lockTimes >= maxTryTimes){

                accountNotLocked = false;

            }

六、登录时是否需要输入验证码

验证码设置前三次（可配置）登录时，不需要输入验证码，当密码尝试次数大于三次时，需要输入验证码，登录方式的一个思路：初始进入登录界面，用户可选择自己的登录方式，我们系统OAuth默认设置了三种登录方式：

用户名+密码登录
用户名+密码+验证码
手机号+验证码登录

系统默认采用用户名+密码登录，当默认的用户名密码登录错误次数（默认一次）超过系统配置的最大次数时，则必须输入验证码登录，当验证码也超过一定次数时（默认五次），都不行则锁定账户二小时之后才可以继续尝试。因为考虑到有些系统可能不会用到短信验证码等，所以这里作为一个扩展功能：如果有需要可以在用户名密码错误过多时，强制只用短信验证码才能登录，且一定要设置超过错误次数就锁定。

1、在自定义的GitEggUserDetailsServiceImpl增加账号判断

            // 从Redis获取账号密码错误次数

            Object lockTimes = redisTemplate.boundValueOps(AuthConstant.LOCK_ACCOUNT_PREFIX + gitEggUser.getId()).get();

            // 判断账号密码输入错误几次，如果输入错误多次，则锁定账号

            // 输入错误大于配置的次数，必须选择captcha或sms_captcha

            if (null != lockTimes && (int)lockTimes >= maxNonCaptchaTimes && ( StringUtils.isEmpty(authGrantType) || (!StringUtils.isEmpty(authGrantType)

                    && !AuthEnum.SMS_CAPTCHA.code.equals(authGrantType) && !AuthEnum.CAPTCHA.code.equals(authGrantType)))) {

                throw new GitEggOAuth2Exception(ResultCodeEnum.INVALID_PASSWORD_CAPTCHA.msg);

            }

            // 判断账号是否被锁定（账户过期，凭证过期等可在此处扩展）

            if(null != lockTimes && (int)lockTimes >= maxTryTimes){

                throw new LockedException(ResultCodeEnum.PASSWORD_TRY_MAX_ERROR.msg);

            }

            // 判断账号是否被禁用

            String userStatus = gitEggUser.getStatus();

            if (String.valueOf(GitEggConstant.DISABLE).equals(userStatus)) {

                throw new DisabledException(ResultCodeEnum.DISABLED_ACCOUNT.msg);

            }

2、自定义OAuth2拦截异常并统一处理

/**

 * 自定义Oauth异常拦截处理器

 */

@Slf4j

@RestControllerAdvice

public class GitEggOAuth2ExceptionHandler {

    @ExceptionHandler(InvalidTokenException.class)

    public Result handleInvalidTokenException(InvalidTokenException e) {

        return Result.error(ResultCodeEnum.UNAUTHORIZED);

    }

    @ExceptionHandler({UsernameNotFoundException.class})

    public Result handleUsernameNotFoundException(UsernameNotFoundException e) {

        return Result.error(ResultCodeEnum.INVALID_USERNAME_PASSWORD);

    }

    @ExceptionHandler({InvalidGrantException.class})

    public Result handleInvalidGrantException(InvalidGrantException e) {

        return Result.error(ResultCodeEnum.INVALID_USERNAME_PASSWORD);

    }

    @ExceptionHandler(InternalAuthenticationServiceException.class)

    public Result handleInvalidGrantException(InternalAuthenticationServiceException e) {

        Result result = Result.error(ResultCodeEnum.INVALID_USERNAME_PASSWORD);

        if (null != e) {

            String errorMsg = e.getMessage();

            if (ResultCodeEnum.INVALID_PASSWORD_CAPTCHA.getMsg().equals(errorMsg)) {

                //必须使用验证码

                result = Result.error(ResultCodeEnum.INVALID_PASSWORD_CAPTCHA);

            }

            else if (ResultCodeEnum.PASSWORD_TRY_MAX_ERROR.getMsg().equals(errorMsg)) {

                //账号被锁定

                result = Result.error(ResultCodeEnum.PASSWORD_TRY_MAX_ERROR);

            }

            else if (ResultCodeEnum.DISABLED_ACCOUNT.getMsg().equals(errorMsg)) {

                //账号被禁用

                result = Result.error(ResultCodeEnum.DISABLED_ACCOUNT);

            }

        }

        return result;

    }

}

3、前端登录页面增加判断，默认采用password方式登录，当错误达到一定次数时，必须使用验证码登录

    requestFailed (err) {

      this.isLoginError = true

      if (err && err.code === 427) {

        // 密码错误次数超过最大限值，请选择验证码模式登录

        if (this.customActiveKey === 'tab_account') {

            this.grantType = 'captcha'

        } else {

            this.grantType = 'sms_captcha'

        }

        this.loginErrorMsg = err.msg

        if (this.loginCaptchaType === 'sliding') {

            this.$refs.verify.show()

        }

      } else if (err) {

            this.loginErrorMsg = err.msg

      }

    }

备注：

一、当验证报401时：

进行 /auth/token 的post请求时，没有进行http basic认证。

什么是http Basic认证？

http协议的一种认证方式，将客户端id和客户端密码按照“客户端ID:客户端密码”的格式拼接，并用base64编码，放在

header中请求服务端。例子如下：

Authorization：Basic ASDLKFALDSFAJSLDFKLASD=

ASDLKFALDSFAJSLDFKLASD= 就是客户端ID:客户端密码的64编码

二、JWT一直不过期：

在自定义TokenEnhancer时，将毫秒加入到了过期时间中，在鉴权解析时，OAuth2是按照秒来解析，所以生成的过期时间非常大，导致token一直未过期。
